“We had warm, sunny weather with strong winds today,” says Beáta. “These conditions are perfect for tiny pollen grains to be lifted and carried in the air.“

Specks of pollen are very small, and when they float through the air they diffractsunlight, forming the softly-colored rings of light in Beáta’s photo. Tiny crystals of ice or droplets of water in the air can do much the same thing – but unlike pollen they do not cause sternutation.
